In Visual Studio and other IDEs, the user picks which configuration to
build from a drop-down, so you can't know which thing you're going to
build at CMake ime. It's a huge pain in the butt for build development
(though quite useful for IDE users).

Some things that help a lot are:

- CMAKE_CFG_INTDIR, which basically resolves to $(OutDir) in VS. Check
  the docs for more details.

- Most of the key properties (COMPILE_DEFINITION, LINK_FLAGS) have
  _DEBUG and _RELEASE variants that are applied only to those build
  configs.

Poke around in the archives with some of those keywords to see more
examples.
